Roland PSB-4U-Repl Replacacement Power Adapter, also replaces ACJ-120 and ACO-120

Product Description

AC Adapter for EM-55/50/30, EP-97/85. May not be OEM.

 

Many different power supplies, such as the AC0120 and the ACJ120, were replaced by the Roland/Boss PSB-4U. Then Roland/Boss replaced this with the PSB-4UREPL, which was really just another one of their power supplies with a wire adapter on the end to change the plug end. Now this new solution has become difficult to get from Roland/Boss as well, so when it is unavailable we are substituting a different brand of power supply with a wire adapter, all of which has the same specifications.
